Claims. (or 230-27 4) Thisinvention relates toelectric fans and more particularly to portable electric fans. i

An object of this inventionis to provide an adjustable electric fan that is adapted to -direct the airflow from various angular directions and to divert or deflect the air streamintermittently.

Another. object of thisrinvention is to provide a unique support for, the 81eQtriC,-fa,n assembly wherein the breeze spreader,the electric motor,

the guard, et cetera, are movable as a. unit relative to the support. 1 t l Another object of this invention is to provide an air driven breeze spreader adapted for angular adjustment.

Other objects and advantages reside the construction of parts, the combination thereof *and the mode of operation as will become more ap parent fromthe following description. y y i In the drawing, Figure l is a front elevational view;

Figure 3 is a rearelevational view;

Figure 4 is a cross sectional view takensubstantially on the line 4 --4 of Figure 2.

Figure 5 is a. cross sectional view taken substantially on the line 5-5 of Figure 1.

The electric fan: disclosed herein includes a pair of angular concentrically disposed supports, one of which is attached to the base and the other. having supported therein the guard, a breeze spreader, an electric motor and the fan blades. The two supports are pivotally attached,

so that the two supports] have a relative movement with respect toeach other, thereby permitting adjustment .ofthe movable support with re spect. to the stationaryjsupport to change the direction of the air flow Oneofthevsupports may be referred to as a Saturn ring or orbital ring support. The details of the structure will appear more fully in connection with the detailed description that follows.

Referring to the drawing, the base I0 forms a front of the base. Thebase is provided with an aperture receiving the reduced portion of a standard 14, held in position by a nut I6 on the under side of the base [0, as clearly seen in Figure 2. This standard l4 provides a support for a plurality of orbital or Saturn-like rings 20, held in.

fixed spaced relation atintervals by tubular spac-v a p p t p i 2o Figure 2 is a side elevational viewlwith the base I shown in section. 1 pintles 32 arewelded to links 33 that provide sup-,

The portion described thus far may-be referred to as the stationary support. i Instead ofa base 10 being used, the standard I4 could. be attached to. wall bracket or it could be suspended from a suitable support from the ceiling; Furthermore, thestandard 14 could be attached to an'extension so as to mount thefan at any desired height above the floor or the sup- The.

The rings 36 and 38 are arranged in spaced relation, as; clearlyshown in Figure'2, The ringl36 supportsa plurality ofy arcuate bracket members), adapted to support a curved end plate lzghaving attached thereto anuelectric motor M. The end plate may also support a suitable switching mechanism 46 for" controlling themoton -'In1order-to guard the;

motor and theparts driven thereby, the arcuate bracket, supports a plurality of wire hoops or rings 48, forminga guard-or, shield. These rings 48, together with the arcuate bracket; cooperatewithqtheend plate 42 to forms. cage fortthe v motor. The shaft of the motor 44 has mount The ring 38 supports a plurality of radially disposed rods or wires 52 held together at the center by an annular disc 54. The annular discil supports a threaded bolt 56 having mounted thereon porting a pair of deflector blades or vanes 62, having the ends attached to an annular ring 64.

A nut 66. threadedly engaging the bolt 56, ten-.

sions a helical spring 68 seated upon the bracket 60, so as to exert a pressure thereon, as will be explained more fully later. The hoop or ring 64 supports an additional pair of deflector blades 10. The bracket 60, the deflector blades or vanes 62 and 10, together with the ring 64 are mounted for rotationupon the bolt 56.

No mechanical drive is provided for the deflector blades and the parts associated therewith. Instead, the vortex formedby the air stream projected by the, fantblades 50 exerts ,a twisting or rotationalflorcef upon the deflector Iblatles, so as to rotate these in the same direction as the direction of rotation of the fan blades; but at a slower.

speed. The speed of rotation of the deflector pair of diametrically disposed supporting members fixedly attached to the Saturn rings, electric fan means pivotally attached to the supporting members, said electric fan means including supporting means, an electric motor supported by said supporting means, a fan driven by the motor, and a breeze spreader mounted in front of the fan blades for rotation vabout an axissubs't'antial-ly parallel to theaxisof rotation of the fan blades, said breeze spreader being driven by the vortex generated by the fan blades, said electric fan means being mounted for bodily adjustblades or vanes is governed by the adjustment of? the nut 66, changing the tensionof the spring 68, which exerts apressureupon fthelbrac'ke't Elli,
